You probably haven't been able to turn on your computer and surf the Internet the last few days without running into a story about Barrie, Ontario area parents claiming their children are being made sick by Wi-Fi radiation in the schools. The media is giving all kinds of attention to one or two scientists who are saying there might be a health concern. Unfortunately, it is giving little more than lip service to the vast bulk of the scientific community who say the opposite.

Sure, many publications have expressed some more or less skeptical opinions - in a wishy-washy kind of way, but no one, anywhere, is telling it straight. No one is saying what should be said. No one is saying that there isn't a shred of credible evidence that there is any harm whatsoever from Wi-Fi signals. No one is saying that the cell phones all these kids have glued to their heads twenty-four hours a day emit considerably more radiation - in the same frequency range - than Wi-Fi transmitters. Heck your DVD player emits more RF radiation than your wireless router, but I don't see any of these parents cutting up their Blockbuster cards.

What needs to be said - loud and clear - is that, in order for the claims of this group to be in any way valid; in order for there to be a health risk from Wi-Fi signals, everything we currently understand about physics would have to be wrong. I'm not talking about a minor correction to our scientific understanding of the world. I mean we'd have to throw the laws of nature out the window and start all over again. Microwave radiation is non-ionizing. That means it doesn't have enough power to damage cells beyond heating them. A typical microwave oven is about 1000 watts. A typical cellphone is less than one watt. What that means is, in order to reheat your cold cup of Tim's to a piping hot, drinkable state (what your microwave would do in about one minute), you'd have to hold your cell phone up to the cup for around seventeen hours...in a shielded box that didn't allow any of the radiation to escape into the environment at large...in an insulated cup that didn't allow any of the heat to escape into the air. OK, let's be honest, it's impossible. And your average Wi-Fi transmitter is about half the power of a cell phone - and typically not held up against your head.

This idea - that Wi-Fi radiation can somehow be harmful to people's health - is what we, in the skeptical community refer to as, "not even wrong." What we mean by that is it is an idea that is so far out of the realm of reason that it's like asking how many pot-roasts the Yankees scored last night. It's a statement that doesn't even make sense in the context of a reasonable discussion. No, these parents are barking up the wrong area rug. They're "not even wrong."

Kelly has come across another list of somebody's opinion of indispensible science fiction novels. He called it 100 more SF books..., but I only count 84. This list overlaps the previous one only a small amount. Once again, I will boldinicize those titles I have read, and add commentary where the inclination strikes me.

Like the previous list, this one seems Philipp K. Dick happy. In fact, there are more Dick books on this one than the last, and only a few of them are duplicates. How many books did this guy write? It seems that there are dozens of novels on this list by authors I have read other works by, but not the ones listed here. Also, there are a good number of books on this list that I've never even heard of before. I guess, between this list and the last, I won't have to look far for ideas when I need something new to read.

The second annual Aurora Jazz+ Festival was held this past Friday night and Saturday. I didn't have a chance to see any of the Friday night performers, but I spent the entire day at the Town Park Saturday listening to the Jazz, Blues, R&B, Pop, Folk, and Rock music line-up the organizers had put together. Along with returning artists like Joel Krivy, Bobby Rice and the Mike Massaro Band, there were a bevy of new performers along for the ride.

The organizers, George and Sher St.Kitts, seem to be dedicated to showcasing as much local talent as possible, and included many amateur, semi-pro, and up and coming York Region performers. The absolute highlight of the show, for me, was Stacey Kaniuk - a cute-as-a-button local girl with a voice that'll knock your socks off. This girl cannot be far from breaking through into the big time. During a hot enough to set the stage on fire rendition of the James Brown hit It's a Man's Man's Man's World, the performers due up next stood on the alternate stage, arms crossed, watching the rug being pulled out from under them. This is a singer-songwriter on her way to the top, mark my words.

Other local performers included the amateur acts Higher Ground and Six Way From Sunday, and aspiring pros Chris Hau, and The Julian Troiano Band. Also in the mix were the traditional Jazz sounds of the After Hours Big Band - another local group - and big name headliner Robert Michaels' cuban/flamenco (cubamenco) guitar stylings.

I was somewhat disappointed with the turnout this year. The park was pretty much empty until evening. Most of the spectators came out to see Robert Michaels play after 8:00PM, but during the day acts were, unfortunately, playing to a sparse littering of no more than a couple hundred people. I'm not sure whether the problem was the timing - on a summer long weekend - or a lack of widespread promotion, or something else - or, more likely, a combination of these factors, but hopefully next year's event will be better attended.
